Travelling by Train in Central and South America
This is a fascinating website which gives information about train travel all over the world. Just reading about the possible trips gives one a yearning to travel!!
There is also a wonderful book by Paul Theroux - "The Old Patagonian Express." He describes his adventures by train all the way from Massachusetts to Patagonia. He's a great read, mostly because he travels the way ordinary folk do.
Boy, would that be exciting!
